Need some tips and tricks for shooting drag racing

Hi everyone,

Tomorrow is the annual Brighon speed trials, basically it is lots of cars and

bikes from classic to modern, racing up a street in brighton at 160mph+. Last

year I was unprepared and had only 1 roll of film, so this year I want to do

better and make the best of this opportunity.

Here is my best shot from last year: http://www.photo.net/photodb/photo?

My equipment:

Canon 20D

EF 70-200 F4L + 1.4 converter

EFS 17-85

Any tips, tricks or useful experiences would be very welcome

Thanks
